All in all the diameter of the light beam should no longer be than 10 ⁇ m.
  • Switching elements are waveguide switches in the present case Channel waveguides, i.e. with two-dimensional throughout Guiding the light in two-dimensional inhomogeneous Refractive index profile understood. The switching will by locally changing a waveguide determining refractive index profile achieved. In these Switching elements, the light comes from an incoming Channel waveguide on at least two output channel waveguides distributed. The ratio of light distribution is, except for the switch losses, essentially freely controllable. So for the expert clear that this is single mode waveguide switch is.
  • the Open space optics is characterized by being vertical to the direction of propagation of light (or individual Rays) there is a homogeneous refractive index, which is only at or near interfaces different media changes. In this free space the light spreads freely, i.e. without leadership effect out.
